Johan Theorin: El guardian de los niños

Mondadori has released this month in Spanish the latest book by Johan Theorin in his Öland Quartet, El guardián de niños, translated by Carlos del Valle Hernández, original title: Sankta Psyko. You can find a review in English at Swedish Book Review. My mistake, sorry. This book is not set in Öland. Therefore it is not the fourth instalment in The Öland Quartet.
